I received a V1ntage ring as a Christmas gift yesterday. My goal was to use it to unlock my Nexus 7 (2013) so I don't have to bother with a password.
I've been trying to get my Nexus to read it reliably and finding it incredibly frustrating. The sweet spot is over the "S". But I've found that unless the ring is off my finger to position it perfectly horizontal and completely flush against the "S", it just won't register. That exact orientation is next to impossible to achieve when the ring is on my finger.
I'm quite disappointed with the ring's performance. I've seen others post that their ring registers when "quite far away" - that's the behavior I was hoping for. I've also seen posts where folks suggest that an Alpha ring reads better. Could that be the solution?
BTW: I don't use a case and I get the same results with both sides of the ring.
